IncFIB plasmids carrying the resistance gene blaCTX-M-15 in ESBL-producing Escherichia coli clones from pediatric patients

Abstract

Even though a small number of ESBL-producing strains was recovered, we evidenced that IncFIB plasmids carry the blaCTX-M-15 gene, highlighting the role of IncF-type plasmids in facilitating the spread and maintenance of ESBL-encoding genes, which further favors the rapid increase of the antimicrobial resistance dissemination in disease-causing E. coli strains in pediatric patients.
